Abstract

La présente invention concerne un microscope électronique confocal à balayage de transmission comprenant un déflecteur de balayage et un correcteur au-dessous de l'échantillon. Le microscope utilise un détecteur de préférence considérablement plus grand que la résolution du microscope et positionné dans le plan de l'image réelle, fournissant un contraste amélioré, en particulier pour les éléments légers.
